Specification of Letters Patent.

Patented Oct. 10, 1911 Application filed December 30, 1910. Serial No. 600,147.

To all whom it may concern:

Be it known that I, ROBERT I. PATTERSON,

a citizen of the United States, residing at 116?; East Main street, Muncie, in the county of Delaware and State of Indiana, have invented a new and useful Lock; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to the art of locks and latches and the like, and it more particularly pertains to a new and useful lock, in which there is involved various novel features of construction.

The invention in its broadest scope, aims as its fundamental object, to provide a lock including a gravitating locking member, which may act as an ordinary latch member at one time for temporarily holding a door or the like in a closed position; and then act at other times as a secure locking bolt, which may be thrown into its keeper for permanently and securely locking the door. hen the gravitating member acts as a latch, the same may be manipulated easily by the knob of the door; but when the gravitating member is utilized as a locking bolt a key is first utilized for partially withdrawing the gravitating member from its keeper, and subsequently the knob of the door completely withdraws it from the keeper.

A further object of the invention is to provide a practicable, durable, simple and inexpensive springless lock.

Another object of the invention is to provide a lock of this design, embodying means for holding the gravitating member or locking bolt entirely out of operative position.

In the drawings, however, there is disclosed certain forms of the invention, but in practical fields these forms may require alterations, to which the applicant is entitled, provided the alterations are comprehended by the appended claims.

The invention comprises further features and combination of parts hereinafter set forth, shown in the drawings and claimed.

In the drawings :Figure 1 is a view of a lock, with the front plate removed, to disclose the various features of the invention. Fig. 2 is a similar view, showing the gravitating member or locking bolt arranged in such a position, that the same cannot be reversed in position without the employment of a key. Fig. 3 is a view similar to Figs. 1 and 2, showing the gravitating member or bolt thrown entirely out of operative position. Fig. 4 is a sectional view on line 4lt of Fig. 1. Fig. 5 is a view similar to Figs. 1, 2 and 3, showing a modified form of means for manipulating the gravitating member or looking bolt. Fig. 6 is a view similar to Fig. 5, showing the same structure as shown in Fig. 5, with the exception that the gravitating member isthrown entirely out of operative position. Fig. 7 is a view similar to Figs. 5 and 6, showing the different arrangement for 1igninipulating the gravitating member or As to the annexed drawings, referring more particularly to Figs. 1, 2, 3 and 4, 1 designates the casing of the look, through which the knob spindle 2 extends. This spindle 2 is provided with a plurality of teeth 8, which are designed to engage the plurality of teeth or lugs 4 of the disk 5. The disk 5 is loosely and eccentrically mounted upon the knob spindle, and is disposed within the annular opening 6 of the gravitating locking member or bolt 7 In order to permit a door or the like, which may be equipped with a lock of this character, to close without manipulating the knob and its spindle, the extension 8 of the locking member or bolt is beveled as shown at 9. It will thus be seen that as a door or the like is completing its full closed position, the beveled portion 9 of the locking member or bolt contacts with the keeper, thus forcing the gravitating member or locking bolt entirely within the casing of the lock. The gravitating locking member or bolt is pivoted upon a stud 10, which projects from the inner wall of the casing. This stud does not fit a complete annular opening or aperture of the gravitating member, but extends through a slot 11 in the member. The purpose of this slot is to permit the gravitating locking member to be slightly elevated, so that the lug 12 of the gravitating member may be changed from the position shown in Fig. 1, to the position shown in Fig. 2. In other words to arrange the lug 12 on the other side of the lug 13 of the casing, as shown in Fig. 2, so that the gravitating member cannot be withdrawn from its keeper by the knob and its spindle. To arrange the lug 12 in the position shown in Fig. 2, a key 14 shown in Fig. 2 is inserted in the key hole of the lock, so that the tongue thereof may engage the peripheral edge of the gravitating locking member.

Pressure is then applied on the key, which 4 cannot be elevated by the knob and its spindle to release it from the position shown in Fig. 2, because of the disposition of the disk 5 with respect to the slot 11. In other words the slot 11 is arranged tangentially with regard to the peripheral edge of the disk 5, thus making it a mechanical impossibility to elevate the gravitating locking member by means of the knob spindle and the disk 5. However, the key as shown in the position in Fig. 2 contactswith the peripheral edge of the gravitating locking member, in such wise'as to permit the locking member to move upon the stud 10. The lifting action of the key is approximately at a slight angle with respect to the stud 10, that is, toward thestud when there is an endeavor to elevate the gravitating locking member. When the gravitating locking member is not in the position shown in Fig. 2, but as shown in Fig. 1 the gravitating locking member may be withdrawn from its keeper by means of the disk 5 and its connection between it and the knob spindle. When the disk 5 is moved in a direction to withdraw the locking member, the peripheral edge of the disk 5 gradually contacts with the wall of the opening 6 of the locking member, thus causing the locking member to oscillate upon the stud 10. It will be noted, however, that no pointed instrument, such as a knife blade or the like, can be inserted between the door and its jamb to elevate the gravitating locking member, because the shoulder 14 of the looking member will contact with the edge of the opening 15 in the casing of the lock.

To hold the gravitating locking member approximately within the casing of the lock and completely out of operative position a pivoted member 16 is mounted upon the pin 17 so as to engage the forward lower corner portion 18 of the gravitating locking member, as shown in Fig. 3. When the locking member completes its movement as shown in Fig; 3 so that the end 19 of the member 16 is free to assume the position shown in Fig. 3 the end- 20 of the member 16 falls bygravitation.

The front plate 22 of the lock is secured in: its place by the screws 23 and the posts 24, in. order to hold the mechanism of the lock in place.

In Figs. 5 and 6' practically the same gravitating locking member is disclosed, with the exception that it is of a little different shape. In Figs. 5 and 6 the disk 5 is entirely dispensed with, and the knob spindle is provided with a plurality of teeth or lugs 25, which mesh with the teeth 26 of the inner wall of the opening 6 of the locking member. I11 these figures the locking member is denoted by the same reference character 7, as in Figs. 1, 2, 3 and 4. The operation of the various parts of the construction of lock shown in Figs. 5 and 6 is identical with that of the other forms, as will be clearly evident.

In Fig. 7 the gravi'tating locking member is pivoted upon the knob spindle, and is rocked by the spindle to withdraw the same from its keeper. In Fig. 7 the knob spindle is designated by the character 28, and is utilized in lieu of the stud 11. The gravitating locking member in Fig. 7 is provided with a slot through which the knob spindle extends. This slot 29 permits the gravitating locking member to be raised by the key 30, in order to dispose the lug 31 upon the other side of the lug 32, in the same manner it is accomplished in the remaining figures of the drawings.

Fro-1n the foregoing it will be clearly noted that there hase been provided a durable, simple and eflicient springless lock, and one which is practical in every feature, and has been found to fulfil the various requirements.
